Differences and information still uncertain
These items are shown explicitly so an approximation is never presented as official data.
Organiser distances and elevation figures are indicative; the rules state that some private or dangerous sections are not necessarily included in the public GPX. Race-day course marking takes priority.
The initial PDF regulations still give starts at 9:00/9:15 and later cutoffs; the current operational page uses 8:00/8:15 and the times included in the listing.
